    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0004518    nuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids.
    GO:0008081    phosphoric diester hydrolase activity    Catalysis of the hydrolysis of a phosphodiester to give a phosphomonoester and a free hydroxyl group.
biological process
    GO:0006281    DNA repair    The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.
    GO:0006974    cellular response to DNA damage stimulus    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
cellular component
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
